I-YTQH450B eguqukayo yokurhabaxa i-crane yinto ekhethekileyo yokugaya kunye ne-truss kunye nokuxinana okupheleleyo kwe-hydraulic kunye nokuphakamisa izixhobo ngokuzimeleyo kuphuculwe ngokweemfuno zentengiso esekwe kwiminyaka emininzi yokuvelisa ubunjineli bokuphakamisa izinto, ukubumbana kunye nezixhobo ezinamandla zokuxinana.
Imodeli inentsebenzo ephezulu, ukuthembeka okuphezulu kunye nembonakalo entle, ihlangabezana ngokupheleleyo nemeko yokuxinana okuguqukayo.
Isetyenziswa ngokubanzi kulwakhiwo lwamashishini kunye nolwaseburhulumenteni, iindawo zokugcina, indlela, iipeyitha kunye nokunye ukuqinisa isiseko, umsebenzi wokwakha onamandla wokuxinana.
